If Cells are Duplicate, then Return a Value

**Ocean Zhang** · 09-24-2009, 09:29 PM

Is there a formula I can use in B2 whereby if the value in A2 is identical to the value in any other cell in column A, then return the value "duplicate" in B2?

=if(Countif(A:A,A2)>1,"Duplicate","")

i need help with a formula.

column A has my order numbers. If I have duplicate order numbers I need in column B to return value from a plus a -1 , -2 , -3 if there are 3 duplicate orders. if nothing is duplicate just return the same number from A.

here is an example

ColumnA ColumnB
1853-583 1853-583
1854-581 1854-581-1
1854-581 1854-581-2
1922-252 1922-252-1
1922-252 1922-252-2
1922-252 1922-252-3

Please help

I want a formula that can decide the trip of a vehicle if it is repeated 2 times in a day

Please do not hijack an old thread!! (See rule 4). Start your own. And, to get a quick answer:

Will you please attach a SMALL sample Excel workbook (10-20 rows of data is usually enough)? However, please give us an indication of the approximate number of rows of data you want the solution to work with (100, 1000, 100,000 or whatever). Please don't attach a picture of an Excel sheet (no-one will want to re-type all your stuff before starting).

1. It does NOT have to be your real sheet - mock up a SAMPLE if you need to. But not 1000's of rows!!! It makes manual checking so tedious. Whatever you do... make sure that all confidential information is removed first!!

2. Make sure that your sample data are truly REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

3. Make sure that your desired solution is also shown (mock up the results manually).

4. Try to avoid using merged cells. They cause lots of problems!

Unfortunately the attachment icon doesn't work at the moment. So, to attach an Excel file you have to do the following: Just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.
